Indwangu ye-retardant flame ekhanyayo inemiphumela yokuvikela yokuvimbela umlilo, ukubambezeleka komlilo, ukumelana nokushisa okuphezulu kanye nesixwayiso sokuphepha.Isetshenziswa kabanzi emikhakheni yokusebenza kochwepheshe enezidingo eziphezulu ezifana nethrafikhi, ukuvikelwa komlilo kanye nogesi, kanye nemikhiqizo yokuvikela ukuphepha enezidingo eziphakeme zokumelana nokushisa okuphezulu kanye nokusebenza kokuhlanza okomile kwesisekelo sendwangu.
Indwangu eyisisekelo yendwangu ekhanyelayo evimbela ilangabi yenziwe ngekotini elimsulwa noma i-aramid, okungelula ukuyisakaza.Ngemuva kokucubungula okukhethekile okunamathelayo, inokusebenza okukhethekile kokunciphisa ilangabi.Lokhu okubalulekile, okungagcini nje ukudlala indima yesixwayiso esikhanyayo kodwa futhi kuphephe futhi kuvimbele ilangabi, ngokungangabazeki kube ukukhetha okuthandwayo kwemikhiqizo yokuphepha emlilweni.Ukusetshenziswa kwendwangu ekhanyayo engacindezeli ilangabi kungabonakala ezingutsheni zokuphepha emlilweni, izicathulo, izigqoko nezinye izinto.
